Final answer:
The frequency of terms like 'physical impairment,' 'impairment,' 'function,' and 'functionality' cannot be determined without the data. However, 'impairment' describes physical limitations and 'function' relates to the ability to perform tasks.
Step-by-step explanation:
In the context provided, it appears that the terms 'physical impairment' and 'function' are being discussed in relation to how disabilities are understood from a sociological perspective. According to the World Health Organization, 'impairment' is used to describe physical limitations, whereas 'disability' is a term used for social limitations. Without the actual data being provided, it is not possible to accurately determine which term appears most frequently in the given data. However, we can deduce that 'impairment' and its derivatives would likely be used when discussing physical limitations, and terms like 'function' or 'functionality' when referring to the ability to perform tasks or actions.
